Antiviren-Software zum Schutz vor Ransomware … die Definition von Wahnsinn?

Posted by: Alex Kurz  /  16 May 2017 13:54:44 BST

In Bezug auf den kürzlich erfolgten globalen Ransomware-Angriff hielten wir es für eine gute Idee, diesen Blog vom 18. April aus dem Englischen zu übersetzen und auch hier zu posten.

Die Geschwindigkeit, mit der sich Ransomware verbreitet, ist überwältigend. Das SonicWall Global Response Intelligence Defense (GRID) Network hat 2015 etwa 3,8 Millionen Angriffe verzeichnet. Im vergangenen Jahr stieg diese Zahl auf 638 Millionen Attacken an. Sie haben richtig gelesen – 638 Millionen! Das sind gut 167 Mal so viele Angriffe wie 2015. Wow! Dabei liegen die Gründe für diese Entwicklung auf der Hand. Es ist ein sehr profitables Geschäft! Ransomware ist eine Klasse von Schadprogrammen, die Ihre Daten verschlüsseln und „Lösegeld“ für die Entschlüsselung verlangen. Die moderne Version von „Geld oder Leben!“ sozusagen.

Was ist also die Antwort? Antiviren-Software, Antiviren-Software und noch mehr Antiviren-Software?

As I’m sure you already know, Friday, 15 May, saw the beginning of a global ransomware attack, hitting hundreds of thousands of businesses around the world.

We would like to share these with you, but before we do that, we cannot stress highly enough the importance of having a good email scanning system in place to avoid malicious content ending up mailboxes and web filters to block dangerous sites in your browsers.

The Heads Up: Solving Ransomware with AV...the definition of insanity?

Posted by: Alex Kurz  /  18 April 2017 10:00:00 BST

 

In the light of the recent global ransomware cyber attack, we felt it appropriate to repost this blog for your information. The original post was dated 18 April, 2017.

The speed at which ransomware is proliferating is mind blowing. In 2015, SonicWall’s Global Response Intelligence Grid recorded around 3.8 million attacks. By last year, that had grown to 638 million. Yes, you read it right – 638 million! That’s a staggering 167 times the number of attacks in 2015. Wow! And it’s easy to see why. Ransomware is particularly profitable for hackers. It’s a nasty type of malware that holds your data hostage by encrypting it and then asking you to pay for a decryption key. Stand and deliver on steroids.

So, what’s the answer? AV, AV and more AV?
